Hello, I'm looking for some expert advice. Jazz and acoustic music are the main fare. I have a home-brew SE 2A3 integrated amp. I also own a pair of rolled rim Loather DX3's. Because of cost, size, etc. considerations, I'm thinking of building and mounting them in BK-16 cabinets. The dimensions are close to Loather recommended Bicor 200 cabinets. Does anyone have a horn program and could tell me what kind of response could I expect from this combo? What construction tweaks or pitfalls should I do or avoid? I know the mounting hole size has to be icreased. Thanx in advance.

As far as I can tell, the DXx and the EXx are electrically and mechanically identical. The only difference is that the EXx has a die-cast basket on the back of the driver. It completely covers the back of the cone and has a bunch of 1/2"-3/4" holes in the perimeter. There is a layer of air-conditional filter foam on the inside of the basket. The basket is glued on with silicon sealant and is easily removed, although this voids your warranty. When you remove the EX basket, you will find a normal DX frame, complete with binding posts. The only thing that you will be missing is a cosmetic cover for the magnet. You will also be surprised at how ridiculously small a neodymium magnet is compared to a ceramic magnet. The theory is that the EX basket reduces reflections from the rear of the speaker cabinet from getting back into the cone. Maybe so. Perhaps this is effective in horn cabinets. However, when using an EX in a resonant cabinet, I find that the basket prevents the driver from loading the cabinet properly. A DX driver works much better in a resonant cabinet, and you save $150 to boot. Bob
